This is an archive of the original data built by Epic Games on May 19 2011 for Gears of War 3 for PS3 systems. Originally created during an engine test, and leaked 10 years ago and remained unusable data while circulating between collectors and exchanging hands. I was the first person to get this data working 9 years later, and decided now that it's time to release it on the 10th anniversary of this build being made (May 19 2021). To date, this is the only Epic-made data for a PS3 version of the game, as all others have been made with leaked source code.
Within the archive you can find the original rar (labeled Gear_PS3) containing cooked untouched data, the GP3 for generating a disc (wont work due to missing data), ICON0.PNG (placeholder).
Additionally, you can find the fixed and bootable data in the archive as well.This data as closely matches the intended disc image layout but instead boots from the HDD. To make use of this, you will need a PS3 devkit. THIS WILL NOT WORK ON NORMAL PS3 SYSTEMS, YOU NEED THE EXTRA RAM FROM A DEVKIT. RPCS3 is an option but not as of today (it will boot to the title screen though). Simply FTP the BLUS54687 folder into the path /dev_hdd0/game/ and rebuild database. Set the devkit release check mode to Release, and then it should work. A keyboard will be required to load maps and game modes.
